Abstract
The incidence of black heart in pineapples that were stored at temperatures from 4-8°C and followed by seven days at 20°C initially increased as the period of storage at low temperature increased. A maximum level of black heart was attained after 10-20 days at low temperature, but longer periods at low temperature decreased the incidence of the disorder. Fruit held at HFC, however, showed no reduction in the maximum black heart level during 50 days' storage.
